To all whom it may concern:

Be it known that 1, CHARLES C. FARDON,

ger the tank or its contents as where lightning might ignite theescaping gas and cause fire.

A further object of this invention is to provide a tank with alealoproot joint between the roof and the wall of saidtank, it beingwell known that it is commonly a great loss and annoyance when the-jointbetween the roof and tank is unsealed.

.With the foregoing and other objects in view the invention consists inthe details of construction, and in the arrangement and combination ofparts to be hereinafter more fully set forth and claimed.

In describing the invention in detail, reference will be had to theaccompanying drawings forming phrt of this specification wherein likecharacters denote corresponding parts in the several views, and inwhich- Figure l'illnstrates a view in elevation of a tank with the venttubes, the supports for the vent tubes being shown in section; and Fig.Qillustrates a vertical sectional view of a fragment of the tank showingthe roof and the joint between the root and the tank. in these drawings3 denotes a tank, 4: the usuai board or plank covering for the '-tank, 5the sheathing or metal covering for the wooden portion of the root, thesaid sheathin 5 extending beyond the wall of the said tank and embracingthe flange 6 of the angle iron 7, the said angle iron having one wing 8thereof lying parallel with the "side of the tank and secured thereto byfastenings 9 which may be in the form of bolts rivets or the like. It isprobably preferable, althougi'i not essential 1n all instances, that apacking 10 be interposed between the angle iron and the wall of thereceptacle so to prevent formationv cit crevices or poo els in which gasmight lodge.

The sheathing 5, as stated, embraces the edge of the flange (3 and thesheathing is secured to the said flange by the iastenings it which maycomprise bolts, rivets or the like.

, The metal covering is then caused to em brace the angle iron and theopposite edge of the metal covering is bent to lie between the angleiron and the tank and it is clamped in place and firmly held by thetagtenings which are employed tosecure the angle iron to the tank. It ispreferable also to utilize a metal covering 13 for embracing the angleiron 7, so as to obviate the formation 01 pockets for the collection ofgas and as a further means for sate-guarding the structure againstleaksand the formation of pockets, the space incloscd by the angle ironand the metal covering is supplied with a filler l-l consisting of anasphalt prepara tion. v

Fron'i the foregoing,,it will be seen that, in view of: the Itaet thatthe usual pocket formed by the angle iron (5, is tilled by the material14, which is held in position by the asbestos 13, any danger of gaswhich might leak from the tank and collect at this point is obviated,thereby lessenin f the liabilit of explosion or fire, due to lightningigniting esc: ping gas.

.li claim l. A storage tank having a root including a metal coveringtherotor, an angle iron secured to the tank ear its upper end, the saidcovering being extended to en'ibraee the edge of a flange of the angleiron, means for securing the covering to the said ai'igle iron, a metalmember secured to the root and embracing the angle iron and having itsedge il'llklPOSQCl between the said angle iron and the tank, and afiller between the metal member and the angle iroin 2. A storage tankhaving a root including a metal covering therefor, an angle iron:

- secured to the tank near its upper and, the I sand covering bemgextended 10 embrace the of the of the zmg ie iron means for secur-m thecovemn to the smd an le b 1 L EK'OD, a metal member secuyea w L118 lOOIand Lm'biucing the ang'm iron and having its edge; int rpnsed betweenthe said angle iron and ihe tank, and suitable insulation and crevicefilling material associated with the tank, angle iron and metal member.

In testimony whereof, I hereunm affix my 15 siglmiaura in the presenceof two 'witnes es.
